--- Comment #11 from Vadim Zeitlin <vz-gcc at zeitlins dot org> --- (In reply to Alexander Monakov from comment #8) > Vadim, can you please check if the issue is reproducible on preprocessed > (-E) input as well, Yes, it is. I've actually started with the preprocessed input initially, but it was so big (~90kLoC) that delta didn't make much progress with it after running for ~2 days, which is why I finally didn't use it. And preprocessing the current test case still results in a ~55kLoC file, so I've had to compress it to attach it here. > and if so, attach the preprocessed testcase so people > can try to repro it without downloading Debian's MinGW headers? Sure, done now. Thanks again for looking at this!
